The SR130 rotary drilling rig developed by Sany Heavy Duty Pile Co., Ltd. was recently assembled in Beijing. The research and development of this product has successfully filled the blank of the modern underground construction field dedicated to the construction of rotary drilling rigs for civil engineering construction.
The SR130 rotary drilling rig belongs to the extension of the series of rotary drilling rigs in foundation-based construction machinery. The product adopts the mature excavator chassis of the 31st and the loading device of the SR series rotary drilling rig, through the bold reform of the working device. Innovation, adopting the international popular bite pile method, using the new design concept to meet the requirements of green environmental protection and the era of building a conservation-oriented society and a harmonious society, so that the products have a good market prospect.
The in vitro culture of cells and tissues has become an indispensable part of life research and practice. A wide variety of cell types are cultured, from viruses to bacteria and fungi, from human cells to animal and plant cells. Some cells and tissues can be grown in suspension, but a considerable number of mammalian cells require surface attachment. Therefore, in addition to good transparency, non-toxicity and sterility, the culture flasks, Culture Plates and culture dishes used to provide the in vitro culture environment of cells also need to be surface-modified to enable them to adhere, divide and grow.
